cos_decay

cos_decay(x, amp=1.0, tau=1.0, freq=0.15915494309189535, phase=0.0, baseline=0.0)

Cosine function with exponential decay.

$$y=\mathrm{a}\mathrm{m}\mathrm{p}\cdot e^{-x/\tau }\cos (2\pi \cdot \mathrm{f}\mathrm{r}\mathrm{e}\mathrm{q}\cdot x+\mathrm{p}\mathrm{h}\mathrm{a}\mathrm{s}\mathrm{e})+\mathrm{b}\mathrm{a}\mathrm{s}\mathrm{e}\mathrm{l}\mathrm{i}\mathrm{n}\mathrm{e}$$
